DOOR-LOCK.

Specification'of Letters Patent. Patented Oct. 26 1920 Application filed October 8,1919. Serial No. 329,336.

To all whom it may concern:

Be it known that 1, JAMES C. HUTSON a citizen of the United States, residing at M15 soula, in the county of Missoula and State of Montana, have invented certain new and useful Improvements in Door-Locks, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a door lock,and has for its obj ect the construction ofan efficient and durable lock that may be positioned upon two sliding doors, or upon a frame and a sliding door for holding the door or doors in a locked position, at the will of the operator. I

lVith this and other objects in view, my invention comprises certain novel constructions, combinations,.and arrangements of parts as will be hereinafter specifically described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims,

In the drawings,

Figure '1 is a viewin side elevation of a lock constructed in accordance with the pres eut invention. i r I Fig. 2 is an elevated edge view of the stationary and pivoted plates.

Fig. 3is a view in elevation of the edge of the lock, showing the pivoted plate in a set position for receiving the sliding plate.

Fig. leis a fragmentary plan view of the sliding plate. r

Fig. 5 is a perspective view of the link.

Fig.5 is an end view taken on line 6-6, Fig. 2, looking in thedirection of the arrow.

Referring to the drawings by numerals, 1 designates preferably a door frame, and 2 the sliding door, although my lock willlwork just-as well if mounted upon two sliding doors. Mounted upon the frame or door 1 isa primary plate 3, and fastened to door 2 is an auxiliary plate 4. Pivotally mounted,

as hereinafter described, upon the primary plate '3 is plate 5. V

The inner end of auxiliary plate 1 is provided with parallel lugs 6; these lugs 6 are provided with elongated apertures 7.

The primary plate is provided at its upper edge with an outwardly-bent grip 8, which is provided for enabling the operator to quickly grip the plate, and if the plate be on a sliding door, then draw the door away from the door 2 to separate the doors when desired; plate 3 is provided with a plurality of parallel reinforcing webs or ribs 9 integral with the grip 8, for strengthening the grip and the plate where this manual strain is exerted for opening or closing the door 1, in such cases where 1 is a door instead ofa frame, the support upon which plate 3 is fastened being a door instead of a frame.

On the inner edge of plate 3 are right angle flanges 10, 10 between which pass the inner lug ends of the auxiliary plate 4:.

Formed upon the primary plate 3 are parallel, substantially U-shaped standards 11 and 12, within which standard 11 is pivotally fastened link 13. This link 13 is provided with a body 14 having an upper, ex'

tension 15, in which are formed apertures 16, which apertures receive suitable fastening means for attaching the flat upper end 15 of the link of the under face of the pivoted plate 5. The lower end of the body 14 a is rolled as at 17, within which rolled portion 17 is positioned fastening. bolt18; bolt 18 extends through the primary standard 11,

and its outer end is apertured for receiving a seal lock 19 for preventing the bolt from being removed without detection. A catch link20 is providedwith notch 21 which'is bent at 22, placing its lower base portion 23 at right angles to the upper part of the link, and the base portion 23 is rolled like 17 (Fig. 5), in which rolled lower portion is positioned the fastening bolt 24. This catch link 20 is slidably mounted in an aperture 25 near the outer end of pivoted plate 5, and the catch link is slidably mounted in this aperture so that when it is desired to fasten the pivot plate 5 in an open position, the plate can be hooked in the notch 21 as clearly shown in Fig. 3, to allow the ready positioning of the locked inner end of aux-' plate 3-,-and a lug 27 is secured to the under I face of the pivoted plate 5; coil spring 28 has itsends mounted upon these. lugs 26 and 27, whereby the spring is prevented from beingdisplaced from between the plates 3 and 5, thereby causing an outward pressure to be exerted by the spring, upon the pivoted plate, whereby the inner end of the pivoted plate is normally held close upon the primary plate 3.

The inner end of the pivoted plate is broadened or widened as at 5 (Fig. 1), and

this broadened inner end 5 is slotted, and at its edges are formed upstanding elongated apertured lugs 6, similar in structure to lugs e on the auxiliary plate 4, and this broad portion 5 is provided with an upwardlyextending guiding flange 29 which assists in directing the parallel lugs 6 in between the parallel lugs G of the pivoted plate 5. When the lugs 6 and 6 are in their registering position, a suitable lock can be threaded through or positioned in the elongated registering apertures of these lugs, and the door or doors locked at the will of the operator.

I wish it to be understood that in carrying out the manufacture of this invention on a large scale, certain minor details or alterations may be found desirable or necessary, to one skilled in the art to which this invention relates, and, therefore, I reserve the right to make such minor alterations or changes as shall fall within the scope of the appended claims.

What I claim is:

1. In a lock of the class described, the combination of a primary plate provided with a pair of transversely alined flanges only at its inner end, an auxiliary plate adapted to have its inner end pass between said flanges and rest against the primary plate, said auxiliary plate provided at its inner end with a pair of parallel outwardlyextending apertured lugs, a broad locking plate attached to said primary plate and be ing adapted to rest upon the auxiliary plate and behind said flanges their entire length, and said locking plate provided with a pair of parallel outwardly-extending apertured lugs adapted to register with the apertured lugs on the auxiliary plate.

2. In a lock of the class described, the combination with a primary plate, of an auxiliary plate provided with fastener-receiving means adapted to engage the primary plate, a movable plate carried by the primary plate and provided with fastener-receiving means registering with the fastener-receiving means of the auxiliary plate, a catch link pivotally mounted upon the primary plate and extending through the movable plate, said catch link comprising a body having near its lower end a rounded or rolled portion at right angles'to the body and having a notch formed in its body intermediate its ends for receiving a portion of the movable plate for holding the movable plate temporarily in a set position.

3. In a lock of the class described, the combination with a primary plate, of an auxiliary plate co-acting with said primary plate, a pivoted plate carried by said pr1- mary plate, said pivoted plate and auxiliary plate provided with cooperating fastenerreceiving means, said primary plate provided with a substantially U-shaped standard, a bolt extending through said standard, a catch link provided with a supporting body being twisted near its end and its base rolled to surround the bolt, and a catch link provided with a notch above the rolled portion for engaging the pivoted plate and holding the pivoted plate in an open position.

4. In a lock of the class described, the

combination with a primary plate, of an auxiliary plate adapted to rest against the primary plate, a pivoted plate, a substantially U-shaped standard fastened to the primary plate, a supporting link having its upper end bent at an angle to its body and having its lower end rolled, fastening means extending through the standard and through the rolled portion of said link for fastening the link to the standard, means attaching the upper angularl -disposed part of thev link to the pivoted p ate, and means formed upon the pivoted plate and the auxiliary plate for receiving and supporting fastening means.

5. In a lock of the class described, the combination of a primary plate provided at its inner end with transversely alined, spaced right-angle flanges, an auxiliary plate adapted to have its inner end pass between the inner ends of said flanges, said auxiliary plate provided at its inner end' with parallel lugs, said lugs provided with elongated ai iertures, a pivoted plate pivotally mounted upon said primary plate, said pivoted plate having its inner end lying flat with the primary plate and being broadened or widened, said broadened inner end of the pivoted plate resting behind the transversely-alinedflanges and provided with an elongated aperture adapted to receive the parallel lugs of the auxiliary plate, said broadened inner end of the pivoted plate provided with parallel, apertured lugs contiguous to the edges of the receiving aperture thereon, and said lugs registering with the lugs on the auxiliary plate, and said broadened inner end of the pivoted plate provided with an outwardly-extending guiding flange contiguous to and between the inner ends of 'the alined flanges of the primary plate.

In testimony whereof I hereunto aifix my signature.

JAMES C. HUTSON.
